摘要: 试验旨在探讨不同酸性洗涤纤维(acid detergent fibre,ADF)水平对2岁新西兰种公兔精液品质、血清生化指标和生殖激素的影响。选用2岁龄种公兔80只,按体重随机分成4组,每组20个重复,每个重复1只,分别饲喂ADF水平为13%、16%、19%、22%的日粮。结果表明, ADF水平对试验兔射精量和精液品质影响差异显著(P<0.05), 试验3组射精量显著高于试验1、2组(P<0.05),试验3、4组精液密度显著高于试验1、2组(P<0.05),试验3组精子活力显著高于其它3组(P<0.05);ADF水平对试验兔血清总蛋白和总胆固醇影响差异显著(P<0.05),试验2、3组总蛋白显著高于试验1组(P<0.05),试验1组胆固醇显著高于其它组(P<0.05);ADF水平对试验兔生殖激素含量影响显著(P<0.05),试验2组促黄体素、睾酮和雌二醇显著高于其它3组(P<0.05),试验2组促卵泡素显著高于试验1、4组(P<0.05)。因此,2岁新西兰种公兔适宜的ADF 水平应为16%~19%,甚至可以提高到22%。

Abstract: The experiment was conducted to study the effects of dietary acid detergent fibre(ADF) levels on sperm quality, serum biochemical parameters and generative hormones in adult New Zealand breeder male rabbits. Eighty 2-years-old breeder male rabbits were randomly assigned to 4 groups with 20 replicates in each group and 1 rabbit in each replicate. Rabbits in the 4 groups were fed with 4 ADF levels(13%,16%,19%,22%) respectively. The results were listed below: Dietary ADF levels had significant influence on the sperm quality(P<0.05),the sperm volume of group 3 were significantly higher than those of group 1 and group 2(P<0.05),the sperm concentration of group 3 and group 4 were significantly higher than those of group 1 and group 2(P<0.05), the sperm motility of group 3 were significantly higher than those of the other groups(P<0.05).Dietary ADF levels had significant influence on the serum biochemical parameters(P<0.05), the contents of total protein (TP) of group 2 and group 3 were significantly higher than that of group 1(P<0.05), the cholesterol(CHO) of group 1 were significantly higher than those of the other groups(P<0.05). Dietary ADF levels had significant influence on the serum generative hormones(P<0.05), the LH, T and E2 of group 2 were significantly higher than those of the other groups(P<0.05),the FSH of group 2 were significantly higher than that of group 1 and group 4(P<0.05). In conclusion, the appropriate dietary level of ADF for the 2-years-old breeder male rabbits was 16% to 19%, even 22%.
